In the following description of the various examples, reference is madeto the accompanying drawings, which form a part hereof, and in which isshown by way of illustration various examples in which aspects of thedisclosure may be practiced. It is to be understood that other examplesmay be utilized and structural and functional modifications may be madewithout departing from the scope and spirit of the present disclosure.

FIG. 1 depicts an isometric view of an insulating device 100. In oneexample, the device 100 may be configured to store a volume of liquid.The device 100 may comprise a container 102 and a lid or closure 104that may be removably coupled thereto. In one example, the container 102may be substantially cylindrical in shape. As such, in one example, thecontainer 102 may be referred to as a canister. In various examples, thecontainer 102 may be referred to as a bottom portion, base, or insulatedbase structure having a substantially cylindrical shape.

FIG. 2 depicts a cross-sectional view of the device 100. As such, thedevice 100 may include a first inner wall 106 and a second outer wall108. A sealed vacuum cavity 110 may be formed between the first innerwall 106 and the second outer wall 108. This construction may beutilized to reduce heat transfer through the first inner wall 106 andthe second outer wall 108 between a reservoir 112, which is configuredto receive a mass of liquid, and an external environment 114. As such,the sealed vacuum cavity 110 between the first inner wall 106 and thesecond outer wall 108 may be referred to as an insulated double-wallstructure. Additionally, the first inner wall 106 may have a first end116 that defines an opening 118 extending into the internal reservoir112 for receiving a mass of liquid. The second outer wall 108 may forman outer shell of the device 100. The second outer wall 108 may beformed of a side wall 120 and a bottom portion 122, which forms a secondend 124 to support the device 100 on a surface. A seam 123 can be formedbetween the second outer wall 108 and the bottom portion 122. In oneexample, the bottom portion 122 can be press-fit onto the second outerwall 108. Additionally the bottom portion 122 can be welded to thesecond outer wall 108. The weld may also be polished such that the seamdoes not appear on the bottom of the device 100.

The bottom portion 122 may include a dimple 126 that is used during avacuum formation process. As shown in FIG. 2, the bottom portion 122covers the dimple 126 such that the dimple 126 is not visible to theuser. The dimple 126 may generally resemble a dome shape. However, othersuitable shapes are contemplated for receiving a resin material duringthe manufacturing process, such as a cone, or frustoconical shape. Thedimple 126 may include a circular base 128 converging to an opening 130extending into the second outer wall 108. As discussed below, theopening 130 may be sealed by a resin (not shown). During the formationof the vacuum between the first inner wall 106 and the second outer wall108, the resin may seal the opening 130 to provide the sealed vacuumcavity 110 between the first inner wall 106 and the second outer wall108 in formation of the insulated double-wall structure.

In alternative examples, the dimple 126 may be covered by acorrespondingly-shaped disc (not shown) such that the dimple 126 is notvisible to the user. The circular base 128 may be covered by a disc,which can be formed of the same material as the second outer wall 108and the first inner wall 106. For example, the first inner wall 106, thesecond outer wall 108, and the disc may be formed of titanium, stainlesssteel, aluminum, or other metals or alloys. However, other suitablematerials and methods for covering the dimple 126 are contemplated asdiscussed herein and as discussed in U.S. application Ser. No.62/237,419, which is incorporated fully by reference as set forth fullyherein.

As such, the container 102 may be constructed from one or more metals,alloys, polymers, ceramics, or fiber-reinforced materials. Additionally,container 102 may be constructed using one or more hot or cold workingprocesses (e.g. stamping, casting, molding, drilling, grinding, forging,among others). In one implementation, the container 102 may beconstructed using a stainless steel. In specific examples, the container102 may be formed substantially of 304 stainless steel or a titaniumalloy. Additionally, one or more cold working processes utilized to formthe geometry of the container 102 may result in the container 102 beingmagnetic (may be attracted to a magnet).

In one example, the reservoir 112 of the container 102 may have aninternal volume of 532 ml (18 fl. oz.). In another example, thereservoir 112 may have an internal volume ranging between 500 and 550 ml(16.9 and 18.6 fl. oz.). In yet another example, the reservoir 112 mayhave an internal volume of at least 100 ml (3.4 fl. oz.), at least 150ml (5.1 fl. oz.), at least 200 ml (6.8 fl. oz.), at least 400 ml (13.5fl. oz.), at least 500 ml (16.9 fl. oz.), or at least 1000 ml (33.8 fl.oz.). The opening 118 in the container 102 may have an opening diameterof 64.8 mm. In another implementation, the opening 118 may have anopening diameter at or between 60 and/or 70 mm. The reservoir 112 mayhave an internal diameter 113 and a height 115 configured to receive astandard-size 355 ml (12 fl. oz.) beverage (aluminum) can (standard 355ml beverage can with an external diameter of approximately 66 mm and aheight of approximately 122.7 mm). Accordingly, the internal diameter113 may measure at least 66 mm and can be at or between 50 mm and/or 80mm. The height 115 may measure at least 122.7 mm and can be at orbetween 110 mm and/or 140 mm. In one example, the container 102 may havean outer diameter 103 measuring approximately 76.2 mm. In otherexamples, the outer diameter 103 may be at between 60 and/or 90 mm.Further, the lid 102 may have an outer diameter 132 approximately equalto the outer diameter 103 of the container 102.

Additional or alternative methods of insulating the device 100 are alsocontemplated. For example, the cavity 110 between the first inner wall106 and the outer walls 108 may be filled with various insulatingmaterials that exhibit low thermal conductivity. As such, the cavity 110may, in certain examples, be filled, or partially filled, with air toform air pockets for insulation or a mass of material such as a polymermaterial, or a polymer foam material. In one specific example, thecavity 110 may be filled, or partially filled, with an insulating foam,such as polystyrene. However, additional or alternative insulatingmaterials may be utilized to fill, or partially fill, the cavity 110,without departing from the scope of these disclosures.

Moreover, a thickness of the cavity 110 may be embodied with anydimensional value, without departing from the scope of thesedisclosures. Also, an inner surface of one or more of the first innerwall 106 or the second outer wall 108 of the device 100 may comprise asilvered surface, copper plated, or covered with thin aluminum foilconfigured to reduce heat transfer by radiation. It is also contemplatedthat the lid 104 may be insulated using the techniques described herein.

As depicted in FIG. 2, the lid 104 may be configured to beremovably-coupled to, and seal the opening 118 in the container 102.FIG. 3 depicts a top view of the lid 104 with an outer diameter 132. Inone example, outer diameter 132 may measure approximately 75.8 mm. Inanother example, outer diameter 132 may measure at or betweenapproximately 60 and/or 90 mm. However, outer diameter 132 may beembodied with any dimensional value without departing from thesedisclosures. The lid 104 may be formed as a frustoconical surface 134spaced between a circular top surface 136 and a cylindrical surface 138.A handle 140 may be integrally-molded to the frustoconical surface 134,and coupled to the lid 104 at two diametrically-opposed points 142 and144. In one example, the handle 140 may have an outer surface 146, withat least a portion of the outer surface 146 having circular curvatureconcentric with, and having a radius equal to, the cylindrical surface138. For example, the circular curvature of the outer surface 146 may beconcentric with, and have a radius equal to the cylindrical surface 138between points 148 and 150, and also between points 152 and 154.Accordingly, this portion of the outer surface 146 of the handle 140 mayhave a radius of curvature equal to 37.9 mm. In another example, thisportion of the outer surface 146 the handle 140 may have a radius ofcurvature measuring at or between 30 and/or 45 mm. However, this radiusof curvature of the handle 140 may have any dimensional value, withoutdeparting from the scope of these disclosures.

FIG. 4 depicts an front view of the lid 104. Accordingly, the handle 140may have an inner surface 156 that has an overmolded grip 158. In oneimplementation, the overmolded grip 158 may be an elastomer, such assilicone rubber. However, any polymer may be utilized as the overmoldedgrip 158. Further, in another implementation, the inner surface 156 ofthe handle 140 may not include the grip 158, without departing fromthese disclosures. In one example, the cylindrical surface 138, thefrustoconical surface 134, the circular top surface 136, and the handle140 may be collectively referred to as an upper portion 160 of the lid104. The lid 104 may have a lower portion 162 that has a cylindricalsidewall 164 with a threaded area 166 and a channel 168 extending arounda lower area of the sidewall 164. The channel 168 may be configured toretain a gasket 170. In one example, a radially and axially extendingflange 161 can extend from the lower portion 162 of the lid 104. Theradially extending portion of the flange 163 in combination with ashoulder 165 forms the channel 168 for receiving the gasket 170. Thehollow structure of the flange provides additional volume for thecontents in the device. However, it is also contemplated that thechannel could be formed as a reduced diameter portion in the lid 104such that the reduced diameter portion is a solid non-hollow structure.In one example, the gasket 170 may be a c-shaped or u-shaped gasket asshown in FIG. 5. However, different gasket geometries are contemplatedin this disclosure. Additionally it is also contemplated that the gasket170 could be placed at other locations along the lid 104. For example,the gasket 170 can be placed between the upper portion 160 and the lowerportion 162 at the ridge formed by the upper portion 160 or in a middlearea on the lower portion 162 to aid in sealing the container. Moreover,the gasket 170 could be omitted entirely.

FIG. 5 schematically depicts a cross-sectional view of the lid 104. Inone implementation the lid 104 may be formed using a three-shot moldingprocess, whereby the upper portion 160 may be injection molded with afirst shot of polymer material. Further, the grip 158 may be overmoldedonto the upper portion 160. Further, the lower portion 162 may beinjection molded with a second shot of polymer material. The upperportion 160 may be rigidly-coupled to the lower portion 162 by a thirdshot of a polymer material at the interface 172 between the upperportion 160 and lower portion 162. This third shot of polymer materialis schematically depicted in FIG. 5 as polymer interface element 173. Inthis way, polymer interface element 173 acts like a weld seam to jointhe upper portion 160 to the lower potion 162. This three-shot injectionmolding process may utilize three different polymer materials (one foreach of the upper portion 160, lower portion 162, and polymer interfaceelement 173). In another example, the three-shot injection moldingprocess may utilize a same polymer material for the upper portion 160and lower portion 162, and a different polymer material for the polymerinterface element 173. In yet another example, the three-shot injectionmolding process may utilize a same polymer material for the upperportion 160, the lower portion 162, and the polymer interface element173.

In other implementations, the lid 104 may be formed using additional oralternative forming processes. For example, the upper portion 160 may beformed by a first molding process (injection molding or otherwise) of apolymer material, and the lower portion 162 may be formed by a secondmolding process of a polymer material. Subsequently, the upper portion160 may be coupled to the lower portion 162 by an alternative couplingprocess, such as, among others, spin welding, gluing, ultrasonicwelding, an interference fit, a threaded coupling, or use of one or morefasteners (such as rivets, screws or bolts) or combinations thereof. Itis also contemplated that the lid 104 can be formed by a singleinjection molding process. In various implementations, the lid 104 maybe formed of a single, or multiple polymer materials, including, amongothers, Acrylonitrile Butadiene Styrene, polypropylene, polyethylene,polystyrene, polyvinyl chloride, nylon, polycarbonate or acrylic, orcombinations thereof. Once coupled to one another, a sealed cavity 174may be formed between the upper portion 160 and the lower portion 162.

The handle 140 may have an opening 176 that is configured to receive oneor more fingers of the user. In one implementation, the opening 176 mayhave a height 178 and a width 180. In one example, the height 178 maymeasure 16.1 mm. In another example, the height 178 may measure at orbetween 10 and/or 20 mm. Further, the width 180 may measure 45 mm. Inother examples, the width 180 may measure at or between 40 and/or 60 mm.As such, the opening 176 may have an opening area measuring between 400and 1200 mm². In one example, the opening 176 may be configured toreceive at least two fingers of an average-sized adult hand. In anotherexample, the opening 176 may be configured to receive at least threefingers of an average-sized adult hand.

FIG. 6 depicts an enlarged cross-sectional view of the lid 104 removablycoupled to the container 102. In particular, FIG. 6 depicts the upperthreaded area 166 of the cylindrical sidewall 164 of the lid 104received by a threaded sidewall 182 of the first inner wall 106 of thecontainer 102. Engagement between the upper threaded area 166 and thethreaded sidewall 182 seals the opening 118 at the first end 116 of thecontainer 102 by urging the gasket 170 into contact with a lip structure184 extending from the first inner wall 106 of the container 102. Assuch, the lip structure 184 is configured to compress the gasket 170 toseal the opening 118. In one example, the lid 104 may beremovably-coupled to the container 102 by engaging the threaded sidewall182 with the threaded area 166 of the cylindrical sidewall 164. As such,the lid 104 may be fully engaged with the container 102 upon rotation ofthe lid 104 relative to the container 102 by any number of revolutions,or by any fraction of a revolution. For example, the lid 104 may befully engaged with the container 102 upon rotating the lid 104, andhence, engaging the threaded area 166 of the cylindrical sidewall 164with the threaded sidewall 182, by approximately ¼ of one fullrevolution, approximately ⅓ of one full revolution, approximately ½ ofone full revolution, approximately 1 full revolution, approximately 2full revolutions, approximately 3 full revolutions, at least 1revolution, or at least five revolutions, among many others.

The cavity 174 may be configured to receive a mass of insulatingmaterial, such as a foam insert. This foam insert may, in one example,be polystyrene. However, additional insulating materials may be utilizedwith the disclosures described herein. In one implementation, the cavity174 may be a vacuum cavity. In another example, the cavity 174 may beconfigured to receive a vacuum-insulated puck structure 186, asschematically depicted in FIG. 7. In one implementation, thevacuum-insulated puck may be in-molded into the cavity 174. Accordingly,the vacuum-insulated puck 186 may have a substantially cylindricalshape, and may be configured with a vacuum cavity (not depicted)configured to reduce heat transfer along an axial direction 188, and/ora radial direction 190. In certain examples, the vacuum-insulated puck186 may be constructed from a metal or alloy, such as stainless steel.In other examples, the vacuum-insulated puck 186 may be constructed froma polymer, a ceramic, or a fiber-reinforced material, or combinationsthereof. Further, the vacuum-insulated puck 186 may have any width 192and/or height 194 dimensional values, without departing from the scopeof these disclosures. In certain examples, the vacuum-insulated puck 186may have a substantially cylindrical shape, but may have chamferedand/or filleted edges. In another example, the vacuum insulated puck 186may have a shape configured to complement the shape of the lid 104 suchthat it has a cylindrical surface corresponding to the cylindricalsurface 138, a frustoconical surface corresponding to the frustoconicalsurface 134, and a circular top surface corresponding to the circulartop surface 136.

FIG. 8 depicts an isometric view of another device 196. Similar todevice 100, device 196 utilizes lid 104, but may be embodied with acontainer 198 having a larger internal reservoir volume than container102. FIG. 9 depicts a cross-sectional view of device 196. The reservoir200 may have a volume of approximately 36 fl. oz. (approximately 1064ml). However, the container 198 may utilize the same opening 118 as thecontainer 102 in order to facilitate removable-coupling to the lid 104.In one example, the container 198 comprises a shoulder region 220.

As such, container 198 may have an outer diameter 222 greater thandiameter 132 of lid 104. Accordingly, an outer wall 224 of the container198 may taper between points 226 and 228 along a shoulder region 220. Inone example, the shoulder region 220 may improve heat transferperformance of the container 198 (reduce a rate of heat transfer) whencompared to a container 102. In particular, the shoulder region 220 maycomprise insulation having lower thermal conductivity (higher thermalresistance/ insulation) than the lid 104 that seals the opening 118. Assuch, device 196 having outer diameter 222 greater than a diameter ofthe opening 118 provides for an increased surface area having thecomparatively higher performance insulation (lower thermal conductivityinsulation).

FIG. 10 depicts an isometric view of another insulating device 202.Again, device 202 may utilize lid 104, but may be embodied with acontainer 204 that has a larger internal reservoir volume than container102, and container 198. FIG. 11 depicts a cross-sectional view of thedevice 202. In one example, the reservoir 206 may have a volume ofapproximately 64 fl. oz. (approximately 1893 ml). However, the container204 may utilize the same opening 118 as the container 102 in order tofacilitate removable coupling to the lid 104.

FIG. 12A depicts an isometric view another implementation of a lid 210.The lid 210 may be similar to lid 104, and may be configured to beremovably-coupled to the container 102. The lid 210 may be embodied witha threaded structure 212 that may interface with the threaded sidewall182 of the first inner wall 106 of the container 102 in order toremovably-couple the lid 210 to the container 102. Lid 210 may alsocomprise an upper portion 214 that may be implemented with geometricalfeatures similar to those described in relation to upper portion 160 ofthe lid 104. The lid 210 may also include an upper gasket structure 216and a lower gasket structure 218. The upper gasket structure 216 may beconfigured to be compressed between the upper portion 214 and the top ofthe container 102. The upper gasket structure 216 may be embodied as ano-ring gasket structure comprising one or more polymeric materials.Further, the upper gasket structure 216 may be embodied with anydimensional values (e.g. inner diameter, outer diameter, and/or height),without departing from the scope of these disclosures. The lower gasketstructure 218 may be configured to seal the opening 118 by compressingagainst the lip structure 184 of the container 102. FIG. 12B depicts anelevation view of the lid 210. It is contemplated that the lid 210 maybe embodied with any dimensional values, without departing from thescope of these disclosures. In one example, the height 220 of the lid210 may measure approximately 70.5 mm. In another implementation, theheight 220 may range between 60 mm or less and 80 mm or more, withoutdeparting from the scope of these disclosures.

FIG. 12C depicts a top view of the lower gasket structure 218. In oneimplementation, the lower gasket structure 218 may have an outerdiameter 222 and an inner diameter 224. Is contemplated that the outerdiameter 222 and the inner diameter 224 may be implemented with anydimensions, without departing from the scope of these disclosures. Inone specific implementation, the outer diameter 222 may measure 61.8 mm.In another example, the outer diameter 222 may range between 50 mm orless and 70 mm or more. Further, the inner diameter 224 may measure 51.2mm. In another example, the inner diameter 224 may range between 40 mmor less and 60 mm or more, without departing from the scope of thesedisclosures. FIG. 12D depicts an elevation view of the lower gasketstructure 218. Accordingly, the lower gasket structure 218 may beembodied with one or more radially-extending vent structures 226. Thevent structure 226 may be utilized to allow internal pressure within thereservoir 112 be released. In one example, the vent structure 226 mayallow a gas pressure within the reservoir 112 to be lowered by allowinga portion of gas to escape through the threaded interface betweenstructures 182 and 212, while preventing a liquid stored in thereservoir 112 from leaking. In one specific example, the lower gasketstructure 218 may be embodied with four radially-extending ventstructures 226, equally spaced around the circumference of the lowergasket structure 218. It is further contemplated that the lower gasketstructure 218 may be embodied with a single vent structure 226, or withtwo, three, or more than four vent structures 226, without departingfrom the scope of these disclosures. In one specific example, a ventstructure 226 may comprise an opening having a height 230 that maymeasure 1.5 mm, and a width 228, that may measure 1 mm. It iscontemplated, however, that the width 228 and height 230 may be embodiedwith any dimensional values, without departing from the scope of thesedisclosures. FIG. 12 D depicts a cross-sectional view of the lowergasket structure 218 along line A-A from FIG. 12C. FIG. 12Eschematically depicts a more detailed view of the elements within area232 in FIG. 12D. Accordingly, FIG. 12E schematically depicts acompressible geometry of the gasket structure 218. In oneimplementation, the lower gasket structure 280 may comprise a c-shapedor u-shaped gasket geometry. Further the gasket structure 218 may beformed from one or more compressible, polymeric materials. In onespecific example, the lower gasket structure 280 may have a 30 durometerhardness value. However, it is contemplated that the lower gasketstructure 218 may be embodied with different hardness values, withoutdeparting from the scope of these disclosures.

FIGS. 13-13E and 14A-I depict another example lid 304 that can be usedin conjunction with the containers discussed herein as well as othercontainer types. The example lid 304 can be configured to have “flip”type of closure such that the lid 304 can be selectably opened or closedby the user by rotating a flip closure 307 into either the openedposition (shown in FIG. 13) or the closed position (shown in FIG. 13A1).In this way, the flip closure 307 can selectively seal an opening 305 ofthe lid 304 to maintain the contents of the container therein duringtransport or storage of the container.

As shown in FIG. 13-13E, the lid 304 can generally include a lid body327 having a top wall 309 and a side wall 364 configured to secure thelid 304 to a container, which in this example can be a threaded area366. The top wall 309 can include an opening 305 for pouring thecontents out of the container. The lid 304 may also include a flipclosure 307, which will be discussed in relation to FIGS. 14A-16D, forselectively sealing or opening the lid 304. The lid body 327 can beformed of a rim 319, an outer cap 329, and an inner cap 331 in athree-shot molding process, which will be discussed in further detailbelow.

Also, as shown in FIG. 13B, similar to the example lid 104 discussedabove, the lid 304 may have a lower portion 362, which can be formed ofportions of the outer cap 329 and the inner cap 331. The lower portion362 has a cylindrical sidewall 364 and comprises the threaded area 366for threading into the container, and a channel 368 extending around alower area of the sidewall 364. The channel 368 may be configured toretain a lower gasket (not shown). The lower gasket can be formed likethe gaskets discussed above, and, as discussed herein, an additionalupper gasket can be placed below the rim 319 above the threaded area 366to provide for additional sealing properties.

Referring again to FIGS. 13-13A2, the top wall 309 can be provided witha central channel 315 which comprises the opening 305 and the flipclosure 307. The flip closure 307 pivots on a pair of pins 313 thatextend from the central channel 315 located in the top wall 309. Thecentral channel 315 may also include two ports 317 that serve as airinlets to ease the pouring of the contents from the container. Thechannel 315 may also include a slot 323 for receiving a correspondingcam 325 on the flip closure 319. The interaction of the cam 325 and theslot 323 helps to maintain the flip closure 307 in the opened positionwhen the user consumes the contents of the container. In addition, therim 319 can include a cutout portion or a notch 321, which is configuredto receive the flip closure 307 when the flip closure 307 is in theopened position. Specifically, the cutout portion 321 on the rim 319 canbe configured to receive the upwardly and outwardly extending tab 335from the flip closure 307 when the flip closure 307 is in the openedposition.

Like in the above example, the lid body 327 can also be formed by athree-shot molding process, where the outer cap 329 can be formed first,the inner cap 331 can be formed inside of the outer cap 329, and the rim319 can be formed on top of the outer cap 329. In one example, each ofthe outer cap 329, the inner cap 331, and the outer cap 329 can all beformed of the same material, such as a suitable polymer, which includesthe polymer types discussed herein. However, the outer cap 329 can beformed clear or opaque such that the user can see the beverage throughthe top of the lid 304. However, it is also contemplated that the outercap 329 can be formed of a non-transparent material, the rim 319 and theinner cap 331 can be formed of a transparent material, or each of theouter cap 329, inner cap 331, and the rim 319 be formed of a transparentor non-transparent material. Furthermore, it is also contemplated thatthe lid body 327 be formed as a single shot of clear, semi-transparent,or non-transparent material. Also, during the formation of the outer cap329, the pins 313 can be inmolded into the channel 315 to provide apivot and location for the flip lid 307.

Referring now to FIGS. 14A-14G1, the flip closure 307 is shown infurther detail. The flip closure 307 may include a knuckle 333configured to articulate on the pins 313 of the lid body 327, anupwardly and outwardly extending tab 335 for grasping by the user toarticulate the flip closure, and a stopper 337 for sealing the opening305 of the lid 304. The flip closure 307 can be formed of a firstsection 307 a and a second section 307 b, which can be formed ofdifferent materials to provide adequate sealing properties and to assistin the assembly of the flip closure 307 to the lid 304. The flip closure307 can also include two protuberances 339, which are configured toalign with the ports 317 when the flip closure 307 is in the closedposition. Additionally, the flip closure 307 includes a cam 325 foraligning with the slot 323 in the channel 315 to secure the flip closure307 in the opened position. Together the knuckle 333, slots 343 formedtherein, and the pins 313 form a hinge for the flip closure 307 toarticulate between the closed position and the opened position. Anexample pin 313 is shown in further detail in FIG. 13C1. As shown inFIG. 13C1, the pin 313 can include a first smooth surface 313 a and asecond textured surface 313 b, which in one example can be a diamondknurled surface 313 b. The first smooth surface 313 a is configured toreceive the slots 343 of the knuckle 333 to provide a smooth operationor rotation of the hinge between the lid body 327 and the flip closure307. The second surface 313 b is configured to be received in thechannel 315 of the lid body 327 and provides a textured surface that canbe received in the channel 315 during the formation of the outer cap.

In one example, the flip closure 307 can be overmolded with a rubbermaterial, which provides sealing properties. In particular, the portionof the stopper 337 that fits into the opening 305 of the lid 304 can beformed slightly larger than the opening 305, such that asealing-interference fit is formed between the stopper 337 and theopening of the lid 304. Thus, when the flip closure 307 is in the closedposition, the interaction between the stopper 337 and the opening 305can form a compression-type of gasket between the opening 305 and thestopper 337 to help prevent the contents from exiting the opening 305.Likewise, the protuberances 339 can be formed slightly larger than theports 317 in the channel to form a sealing-interference fit or acompression-type gasket. In this way, the flip closure 307 helps toprevent the contents of the container (e.g. container 102) from leakingwhen the flip closure 307 is in the closed position. Also, the cam 325can be sized slightly larger than the slot 323 in the channel to formanother interference fit to hold the flip closure 307 in the openedposition to prevent the flip closure 307 from rotating about the hinge333 while the user consumes the contents of the container.

Referring to FIGS. 14F and 14F1, the hinge 333 can be provided with twoslots 343 extending parallel to the hinge and configured to align withthe pins 313 located in the channel 315 on the lid 304. In certainexamples, the slots 343 can each be lined with a gasket (not shown). Asdiscussed below, the gaskets can be inmolded into the flip closure 307during its formation. The gaskets formed in the slots 343 provide anadditional seal, which can be water tight to prevent contents fromcontaminating or corroding the slots 343 of the flip closure 307. Thiscan maintain the cleanliness and prolong the life of the flip closure307 and lid 304, such that the flip closure 307 does not need to bereplaced as often.

Referring now to FIGS. 15A-15C and 16A-16D, the flip closure 307 isformed of a first portion 307 a and a second portion 307 b. The firstportion 307 a is illustrated in FIGS. 15A-15C where 15A shows a top viewof the first portion 307 a, FIG. 15B shows a rear view of the firstportion 307 a, and FIG. 15C shows a side view of the first portion 307a. Also the second portion 307 b is shown in FIGS. 16A-16D, where 16Ashows a bottom view of the second portion 307 b, FIG. 16B shows aninverted front view, FIG. 16C shows a top view of the second portion 307b, and FIG. 16D shows an inverted side view of the second portion 307 b.The flip closure 307 can be formed by a two shot process, where thefirst section 307 a is formed and then the second section 307 b isovermolded over and within the first section 307 a. In one example, thesecond section 307 b of the flip closure 307 can be formed of anelastomer, such as a soft rubber material and may be a thermoset orthermoplastic and can be either a natural or synthetic rubber material.

As illustrated in FIGS. 15A-15C, the first portion 307 b can be providedwith various guides or areas for receiving the second section 307 b orshot of material therein. The first section 307 a can be provided with apost 345 for receiving the cam 325 such that the second portion 307 b orsecond shot of material can be formed surrounding the cam 325. Also thefirst portion 307 b can be provided with two guide flanges 347 forreceiving the second portion 307 b or second shot of material. The firstportion 307 b can also include a downwardly depending tab 349 and anotch 351 such that the second portion 307 b or second shot of materialcan be formed around the tab and within the notch to form the stopper337. Additionally, as illustrated in FIGS. 16A-16C, the stopper 337 andthe protuberances 339 can be formed of the second portion, which asdiscussed above, can be an elastomeric material. The elastomericproperties of the material help to provide seals between the flipclosure 307 and the lid 304.

Also as shown in the cross-sectional views of FIGS. 14E, 14F1, 14G1, theelastomeric material can fill internal voids in the first portion 307 aof the flip closure 307 such that the elastomeric material forms aportion of the internal structure of the flip closure 307. This providesa first area 353 and a second area 355 on the flip closure 307 where thesecond area 355 is more flexible than the first area 353. Specifically,this provides a degree of elasticity in the second area 355 along therotational axis or the knuckle 333 of the flip closure 307 such that theflip closure 307 flexes in order to easily assemble the flip closure 307onto the pins 313. Additionally, during the application of the secondportion to the flip closure 307, the slots 343 may also be provided withthe elastic material to form gaskets therein.

In other examples, the lid 304 discussed herein can also be insulated byone or more of the methods discussed herein. Other suitable methods forinsulating any of the lids discussed herein are discussed in U.S.application Ser. Nos. 14/971,788 and 14/971,779 both filed on Dec. 15,2015, which are fully incorporated herein by reference for any and allnon-limiting purposes.

FIGS. 17 and 18 depict another implementation of a lid 400. The lid 400may be similar to lids 104 and 210 in many respects and like referencenumerals may refer to the same or similar elements in lids 104 and/or210 but include 400 series reference numerals. Lid 400 is different fromlids 104 and 210 in that lid 400 is a two-part lid having a lower cap orportion 403 that may be configured to be removably-coupled to thecontainer 102 and an upper cap or portion 401 that may be configured tobe removably-coupled to the lower cap 403.

Referring first to FIGS. 17A-D, the upper cap 401 may be configured tobe removably-coupled to the lower cap 403. FIG. 17A depicts a top viewof the upper cap 401, where the upper cap 401 has an outer diameter 432.In one example, outer diameter 432 may measure approximately 76.7 mm orabout 77 mm. In another example, the outer diameter 432 may measure ator between approximately 60 and/or 90 mm. However, outer diameter 432may be embodied with any dimensional value without departing from thesedisclosures. As best shown in FIGS. 17A and 17C, the upper cap 401 maybe formed as a frustoconical surface 434 spaced between a circular topsurface 436 and a cylindrical surface 438. A handle 440 may beintegrally-molded to the frustoconical surface 434, and coupled to theupper cap 401 at two diametrically-opposed points 442 and 444. In oneexample, the handle 440 may have an outer surface 446, with at least aportion of the outer surface 446 having circular curvature concentricwith, and having a radius equal to, the cylindrical surface 438. Forexample, the circular curvature of the outer surface 446 may beconcentric with, and have a radius equal to the cylindrical surface 438between points 448 and 450, and also between points 452 and 454.Accordingly, this portion of the outer surface 446 of the handle 440 mayhave a radius of curvature equal to about 37.9 mm. In another example,this portion of the outer surface 446 of the handle 440 may have aradius of curvature measuring at or between 30 and/or 45 mm. However,this radius of curvature of the handle 440 may have any dimensionalvalue, without departing from the scope of these disclosures.

FIG. 17B depicts an elevation view of the upper cap 401. The handle 440may have an inner surface 456 that has an overmolded grip 458. In oneimplementation, the overmolded grip 458 may be an elastomer, such assilicone rubber. However, any polymer may be utilized as the overmoldedgrip 458. Further, in another implementation, the inner surface 456 ofthe handle 440 may not include the grip 458, without departing fromthese disclosures.

The handle 440 may have an opening 476 that is configured to receive oneor more fingers of the user. In one implementation, the opening 476 mayhave a height and a width. In one example, the height may measure 19.2mm. In another example, the height may measure at or between 15 and/or25 mm. Further, the width may measure 45 mm. In other examples, thewidth may measure at or between 40 and/or 60 mm. As such, the openingmay have an opening area measuring between 600 and 1500 mm². In oneexample, the opening 476 may be configured to receive at least twofingers of an average-sized adult hand. In another example, the opening476 may be configured to receive at least three fingers of anaverage-sized adult hand.

Referring now primarily to FIGS. 17D and 18A, the upper cap 401 may beconfigured to be removably-coupled to the lower cap 403. As shown inFIG. 17D, the annular wall 420 may include threads 421 on an innersurface of the annular wall 420. As will be described in more detailbelow, the threads 421 are configured to removably engage similarthreads on the lower cap 403. The upper cap 401 may also include araised circular portion 422 which forms an annular channel 423 betweenthe raised circular portion 422 and the annular sidewall 420. Theannular channel 423 may be configured to accept a gasket (not shown) tocreate a seal against an upper surface of the lower cap 403.

In some examples an annular area 424 may exist between an outsidesurface of the annular wall 420 and inside surfaces of the frustoconicalsurface 434, the circular top surface 436, and/or the cylindricalsurface 438. This annular area 424 may be hollow. The area 424 may alsobe configured to receive a mass of insulating material, such as a foaminsert. This foam insert may, in one example, be polystyrene. However,additional insulating materials may be utilized with the disclosuresdescribed herein. In one implementation, the area 424 may be a vacuumcavity. In another example, the area 424 may be configured to receive avacuum-insulated structure which may be a ring-shaped structure. In oneimplementation, the vacuum-insulated ring-shaped structure may bein-molded into the cavity 424. In certain examples, the vacuum-insulatedring-shaped structure may be constructed from a metal or alloy, such asstainless steel. In other examples, the vacuum-insulated ring-shapedstructure may be constructed from a polymer, a ceramic, or afiber-reinforced material, or combinations thereof. Further, thevacuum-insulated ring-shaped structure may have any dimensional values,without departing from the scope of these disclosures. In certainexamples, the vacuum-insulated ring-shaped structure may have asubstantially cylindrical shape, but may have chamfered and/or filletededges. In another example, the vacuum insulated ring-shaped structuremay have a shape configured to complement the shape of the area 424 suchthat it has a cylindrical surface corresponding to the cylindricalsurface 438, a frustoconical surface corresponding to the frustoconicalsurface 434, and a circular top surface corresponding to the circulartop surface 436. In still other embodiments, the annular area 424 may besolidly filled with the same material as other portions of the top cap401. The top cap 401 may also include a ring shaped lower wall 425extending from a lower end of the annular wall 420 to a lower end ofcylindrical surface 438. This lower wall may enclose the annular area424. In some embodiments, and as shown in FIG. 17D the lower wall 425may include tapered portions 426 which may correspond to similarlyshaped portions on the lower cap 403. The lower wall 425 may beintegrally formed with the other portions of the upper cap 401 or it maybe formed separate from the other portions of the upper cap and laterattached to the upper cap 401. For example, the lower wall 425 mayattached to the other portions of the upper cap 401 using couplingprocesses, such as, among others, spin welding, gluing, ultrasonicwelding, an interference fit, a threaded coupling, or use of one or morefasteners (such as rivets, screws or bolts) or combinations thereof.

In one embodiment, the upper cap 401 may be formed using a two-shotmolding process, whereby the upper cap 401 is formed with a first shotof polymer material and the grip 458 may be overmolded onto the otherportions of the upper cap. As described above, the lower wall 425 maythen be attached to the other portions of the upper cap 401. In otherimplementations, the upper cap 401 may be formed using additional oralternative forming processes. For example, it is also contemplated thatthe upper cap 401 can be formed by a single injection molding process ora three-shot molding process. In various implementations, the upper cap401 may be formed of a single, or multiple polymer materials, including,among others, Acrylonitrile Butadiene Styrene, polypropylene,polyethylene, polystyrene, polyvinyl chloride, nylon, polycarbonate oracrylic, or combinations thereof. In some examples the upper cap 401 orportions of the upper cap 401 may be formed of a transparent material,semi-transparent material, or opaque material.

Referring now to FIGS. 18A-D, the lower cap may have an upper portion470 configured to engage the upper cap 401, a lower portion 462configured to engage the container 102, and a central section 480between the upper 470 and lower 462 portions. The upper portion 470 mayinclude an annular sidewall 472 extending upward from top surface 481 ofthe central portion 480. The annular sidewall 472 may include threads474 corresponding to threads 421 on the upper cap 401. The threads 474may not extend the full height of the annular wall 472. In someexamples, the threads may extend less than ¾ the height of the annularwall 472 or less than ⅔ the height of the annular wall 472.

The lower cap 403 may also have a central portion 480. The centralportion 480 may be cylindrically shaped and have an upper surface 481, alower surface 482, and an outer surface 483. The central section 480 mayhave an outer diameter 484 of about 77 mm. In another example, the outerdiameter 484 may measure at or between approximately 60 and 90 mm. Inanother example the outer diameter 484 of the lower cap 403 may besubstantially similar to the outer diameter 432 of the upper cap 401.However, outer diameter 484 may be embodied with any dimensional valuewithout departing from these disclosures. The annular wall 472 may havean inner diameter 485, shown in FIG. 18B. The inner diameter 485 may beabout 23.3 mm. In another example, inner diameter 485 may measure at orbetween approximately 15 and/or 30 mm. However, inner diameter 485 maybe embodied with any dimensional value without departing from thesedisclosures. The ratio of the outer diameter 484 to the inner diameter485 may be about 3.3 or may be in the range of about 2.7 to about 3.9.

The lower cap 403 may also have a lower portion. The lower portion 462may be similar to the lower portion of lid 210 discussed above. Thelower portion 462 may have a cylindrical sidewall 464 having threads466. The lower portion 462 may also include a lower channel 468extending around a lower area of the sidewall 464 and an upper channel467 extending around an upper area of the sidewall 464. Each of thechannels 467 and 468 may be configured to retain a gasket (not shown inFIGS. 18A-D). The gasket(s) (not shown in FIGS. 18A-D) may be similar tothose described related to FIGS. 12A-12E. For example, the lower cap 403may include an upper gasket structure 416 (not shown) similar to gasket216 and a lower gasket structure 418 (not shown) similar to gasket 218.The upper gasket structure 416 may be embodied as an o-ring gasketstructure comprising one or more polymeric materials. Further, the uppergasket structure 416 may be embodied with any dimensional values (e.g.inner diameter, outer diameter, and/or height), without departing fromthe scope of these disclosures. The lower gasket structure 418 may beconfigured to seal the opening 118 by compressing against the lipstructure 184 of the container 102. It is contemplated that the lowercap 403 may be embodied with any dimensional values, without departingfrom the scope of these disclosures.

Referring now primarily to FIG. 18D, the lower cap 403 may have an upperopening 452 defined by the inside surface of the upper annular wall 472and a lower opening 453 defined by the inside surface of the cylindricalsidewall 464. As shown in FIG. 18D, the diameter of the upper opening452 is less than a diameter of the lower opening 453. In someembodiments the ratio of the diameter of the upper opening 452 to thediameter of the lower opening 453 is less than about ½ or less thanabout ⅔. As shown in FIG. 18D, there may be a transition portion 454wherein the internal diameter of the lower cap reduces from the loweropening 453 to the upper opening 452. The transition portion 454 mayhave a tapered shape such that the angle between inside surface of theupper annular wall 472 and the inside surface of the transition portion454 is greater than 90 degrees. Such a configuration may allow liquid tomore easily flow out of the lower cap 403 when the container 102 is inan inverted position.

Referring again primarily to FIG. 18D, in one embodiment, the lower cap403 may be formed using a two-shot molding process, whereby a firstportion 491 of the lower cap may be molded with a first shot of polymermaterial and a second portion 492 may molded with a second shot ofpolymer material. In other embodiments, the lower cap 403 may be formedusing a three-shot molding process whereby a first portion 491 of thelower cap may be molded with a first shot of polymer material and asecond portion 492 may molded with a second shot of polymer material andthe first portion 491 and the second portion 492 may be rigidly-coupledto each other by a third shot of a polymer material at the interface 493between the first 491 and second 492 portions. In this way, polymerinterface element 493 acts like a weld seam to join the two portions 491and 492. This three-shot injection molding process may utilize threedifferent polymer materials (one for each of portions 491, 492, and493). In another example, the three-shot injection molding process mayutilize a same polymer material for portions 491 and 492, and adifferent polymer material for the polymer interface element 493. In yetanother example, the three-shot injection molding process may utilize asame polymer material for the three portions 491, 492, and 493.

In other implementations, the lower cap 403 may be formed usingadditional or alternative forming processes. For example, the firstportion 401 may be formed by a first molding process (injection moldingor otherwise) of a polymer material, and the second portion 492 may beformed by a second molding process of a polymer material. Subsequently,the portions 491 and 492 may be coupled using an alternative couplingprocess, such as, among others, spin welding, gluing, ultrasonicwelding, an interference fit, a threaded coupling, or use of one or morefasteners (such as rivets, screws or bolts) or combinations thereof. Itis also contemplated that the lower cap 403 can be formed by a singleinjection molding process. In various implementations, the lower cap 403may be formed of a single, or multiple polymer materials, including,among others, Acrylonitrile Butadiene Styrene, polypropylene,polyethylene, polystyrene, polyvinyl chloride, nylon, polycarbonate oracrylic, or combinations thereof. In some examples the lower cap 403 orportions of the lower cap 403 may be formed of a transparent material,semi-transparent material, or opaque material.

Referring now to the upper cap 401 and the lower cap 403, the threads466 of the cylindrical sidewall 464 of the lower cap 403 may be receivedby a threaded sidewall 182 of the first inner wall 106 of the container102. The lower cap 403 may be fully engaged with the container 102 uponrotation of the bottom cap 403 relative to the container 102 by anynumber of revolutions, or by any fraction of a revolution. For example,the bottom cap 403 may be fully engaged with the container 102 uponrotating the bottom cap 403 by approximately 1.5 full revolutions orapproximately 1.75 full revolutions, or 2 or more full revolutions. Thethreads 474 of the upper annular wall 472 of the lower cap 403 may bereceived by the threads 421 of the annular sidewall 420 of the upper cap401. The top cap 401 may be fully engaged with bottom cap 403 uponrotation of the top cap 401 relative to the bottom cap 403 by any numberof revolutions, or by any fraction of a revolution. For example, the topcap 401 may be fully engaged with the bottom cap 403 upon rotating thetop cap 401 by approximately ½ of a full revolution, or approximately ¾of a full revolution, or 1 or more full revolutions. In someembodiments, the number of rotations required to engage the top cap 401with the bottom cap 403 may be less than the number of rotationsrequired to engage the bottom cap 403 with the container 102. Forexample the ratio of number of rotations required to lock the top cap401 to the bottom cap 403 to the number of rotations required to lockthe bottom cap 403 to the container 102 may be less than ½ or less than⅓.

Advantageously the overall resistance and/or coefficient of frictionbetween the top cap 401 and the bottom cap 403 may be less than theresistance and/or coefficient of friction between the bottom cap 403 andthe container 102. Thus, the amount of force necessary to rotate theupper cap 401 relative to the lower cap 403 may be less than the amountof force necessary to rotate the lower cap 403 relative to the container102. Therefore, a user may disengage the top cap 401 from the bottom cap403 without disengaging the bottom cap 403 from the container 102.

In one example, an insulating device formed of a material can include acontainer that has a first inner wall having a first end having athreaded sidewall and an opening extending into an internal reservoirfor receiving liquid, and a second outer wall forming an outer shell ofthe container. The second outer wall can include a second end configuredto support the container on a surface.
